Product Pricing Scenario Calculator
Compare a base price against a higher and lower price using the volume you expect at each.
Price and volume together
Pricing is rarely one number. This scenario view lets you test selling prices against landed cost, fees and target margin so you can see profit under different ticket prices. Use it before a launch or a marketplace move when several fee stacks are in play. Three prices — floor, target and stretch — are enough for a first pass. Related tools: product landed cost, product profit and break-even units. Set percentage targets with reverse margin. If every price looks too tight, revisit cost or channel fees rather than silently erasing margin. Planning estimates only. Channel conflict appears when the same SKU needs different tickets on your site and a marketplace — scenario-plan both fee stacks before you publish. Clearance prices should still clear variable cost unless you are deliberately exiting stock. Record the winning scenario’s assumptions so a future fee change triggers a deliberate revisit.

Worked example
Landed cost £5.15, marketplace fees about 15% of selling price, packaging £0.40. At £12 ticket, fees ≈ £1.80, profit ≈ 12 − 5.15 − 1.80 − 0.40 = £4.65 (~39% margin). At £10, profit falls to about £2.95. At £14, profit rises to about £6.35 — then check whether demand exists at the stretch price.
Limits and assumptions
Demand curves are not modelled — higher prices may sell fewer units. Ads and returns need separate lines for a fully loaded view. Not legal pricing or MAP advice.
Frequently asked questions
When should I run pricing scenarios?
Before listing on a new channel, after fee changes, or when testing a sale price against core margin.
How many prices should I test?
Three is enough for a first pass — floor, target and stretch — then refine.
What if every price looks too tight?
Revisit landed cost, negotiate fees, or change the product brief. Do not silently erase margin.
Should psychological endings come first?
Run margin maths first, then round to £9.99-style endings only if the target still holds.
How do multi-buy prices fit?
Convert to effective price per unit, then run the same cost and fee stack.
